Permian stratigraphic sequences are widely distributed throughout Iranian, making this one of the best locations in the world to study
15 this geological time interval. Nevertheless, some units lack detailed biostratigraphic characterization which is essential for
16 palaeogeographic reconstructions. This preliminary study comprises a palynological assessment of a Permian stratigraphic section
17 cropping out in the Ajabshir area (SW Azerbaijan, NW Iran). The continuous and relatively well-exposed Ajabshir section comprises
18 Unit 3 of the Dorud Formation and the Nesen and Ruteh formation In this area, the Dorud Formation starts with the Unit 3
19 unconformably overlying the Mila Formation, with its lower units missing. Unit 3 (48 m thick) is characterized by sandstones with
20 siltstones and shale intercalations and an upward increase of limestones. The overlying Ruteh Formation (192 m thick) consists
21 mainly of carbonates with scattered coarse sandstone intercalations and dolomitic limestones
